PART D.

A “ wastewater treatment unit ” is defined as a unit operation used to remove pollut ants

from process wastewater. Wastewater treatment units includ e, but are not limited to:

ponds/impoundments, chemical precipitation, pH adjustment , clarification, biological

reactor, thickeners, filters, and constructed wetlands.

NOTE: If a pond/impoundment unit (as defined in Sec tion 4.1) is part of a broader

“wastewater treatment system” containing non-pond uni ts (e.g., a

pond/impoundment unit in a biological wastewater tr eatment system), it is not

considered part of a pond/impoundment system. A " pond/impoundment" is defined as a natural topographic depression, man-made

excavation, or diked area formed from earthen materia ls or man-made materials or a

combination of them, which is designed to hold an accumul ation of liquid process

wastes or process wastes containing free liquids, and which i s not an injection well.

Examples of ponds/impoundments include holding, storage, settling, and aeration pits,

ponds, and lagoons. It does not include building sumps an d outdoor collection/transfer

concrete basins.

A “ pond/impoundment system ” is defined as a system consisting of one or more

ponds/impoundments.

A “ wastewater treatment system ” is defined as a combination of one or more

“wastewater treatment units”, other than ponds/impound ments, designed to achieve

wastewater treatment.

TREATMENT OPERATIONS

INSTRUCTIONS

Part D requests information about all ponds/impoundmen ts used (or planned to be used

or under construction/installation by December 31, 2020) for the storage, treatment,

and/or disposal of process wastewater, residues, or by-prod ucts (or sludges or water

streams containing the residues or by-products) from the co mbustion of coal , petroleum

coke , or oil , including but not limited to fly ash, bottom ash, bo iler slag, or flue gas

emission control residues. Additionally, Part D requests information about wastewater

treatment systems, other than pond/impoundment systems, f or the treatment of

wastewaters from ash handling or FGD operations that ar e located at the plant or are

planned to be located at the plant. Complete Part D if you operate one or more systems,

or if you are currently constructing/installing, or plan ning to construct/install one or more

systems by December 31, 2020.

Refer to the following definitions throughout Part D

.

information is not representative of normal operation s); and note methods used to make

best engineering estimates in the event that exact data are not available. Throughout Part D, information is requested for pond/ impoundment and wastewater

treatment units and systems that are under construction/in stallation, or planned to be
